Hi,
I just got a headache trying to figure out what is wrong with this picture... The call below is from user 38140298 to
38140299 and get canceled. First I sent a complaint to our supplier of residential gateways, but then I figured that it
probably has something to do with my ugly ser.cfg.
The call does get canceled and the phone stops ringing, but I must have done something wrong. The first thing I noticed
was that 38140299 inserts a tag in To header field on cancel, which I thought it wasn't supposed to, since the original
invite (the request to be canceled) does not have tag in To.
When I sent this trace to my friends at Allied, the rg producer, they gave me this answer:
//quote begin
what is strange in the trace you sent us is the 487 sequence.
At first sip server (10.100.10.118) sends to RG (10.5.6.86) a 487 message containing the following tags:
From: 38140298 <sip:38140298 at ipt-server1.ivisjon.no;user=phone>;tag=AABdaQAN2gAAHwxx.
To: <sip:38140299 at ipt-server1.ivisjon.no>;tag=7b6e241b740a185eb7506969073a84c4-dbba.
and after it receives a 487 messages from the other RG (10.5.5.142) containing the following tags:
Via: SIP/2.0/UDP 10.100.10.118;branch=z9hG4bK295f.7009663.0,SIP/2.0/UDP 10.5.6.86:5060;branch=z9hG4bKAwBdaQxx.
From: 38140298 <sip:38140298 at ipt-server1.ivisjon.no;user=phone>;tag=AABdaQAN2gAAHwxx.
To: <sip:38140299 at ipt-server1.ivisjon.no>;tag=AACcBgAJQVeQTwxx.
The issue is that the SS should send the 487 to 10.5.6.86,after it received the 487 from the 10.5.5.142,so that the tag
in the 487 received from 10.5.6.86 would have the correct value.But for stange reason 10.100.10.118 generate a 487
message for 10.5.6.86(with its' own tag=7b6e241b740a185eb7506969073a84c4-dbba) before it received the same massage from
10.5.5.142 (with the correct tag=AACcBgAJQVeQTwxx).
But in this way 10.5.6.86 is not able to recognize the 487,doesn't respond to the multiple messages sent to it,and after
a while sends again a Cancel.
I hope this is clear:the issue is not on Rg behaviour but on 10.100.10.118,why does it generate this 487 messages?
quote end//
The reason I blame the rg is because canceled calls from a Cisco IP-phone to IP-phone looks normal, and also calls from
Cisco gateway to rg. It only happens with calls originating from rg's.
Below is the call trace and my ser.cfg.
I really appreciate if someone can give me some hints here..
